Definitions

  • the present invention refers to the technology of packaging machines and to the packages resulting from said machines.
  • thermosealing devices in cooperation with the side contrasts, perform the thermosealing operations of the prominent longitudinal folds of the film, which is wrapped around the rectangular tube, thus realizing the stiffening at the four corners of the bag resulting from the packaging process of the film, wherein the equipment is set-up with a quadruplet thermosealing equipment whose operational movements are obtained by a single oscillation movement of one single shaft (see US 2002/017077 A1, ref.no. 36), wherein two couples of rectilinear racks transform the angular oscillations of the shaft in opposed simultaneous rectilinear translations of said quadruplet of thermosealing devices (see US 2002/017077 A1, paragraph 0032).
  • the solution proposed by the present invention solves all the problems above in a surprisingly easy, reliable and affordable way.
  • the subject-matter of the invention is an equipment to package rectangular bags with rigid corners, comprising a rectangular forming tube provided with four small fins that are parallel and prominent laterally along the prolongation of two parallel sides of the forming tube, said fins, together with two longitudinal side contrasts, being located parallel to two other sides of the forming tube for creating on a film four prominent longitudinal folds, which remain even when the four short fins end, in order to allow the intervention of four thermosealing devices, said thermosealing devices, in cooperation with the side contrasts, being constructed for performing thermosealing operations of the prominent longitudinal folds of the film, which is wrapped around the rectangular forming tube, thus realizing the stiffening of the four corners of the bag resulting from the packaging process of the film, wherein the equipment is set up with a quadruplet of thermosealing devices whose operational movements are obtained by a single oscillating movement of one single shaft having two long toothed zones each engaging with a couple of rectilinear racks, the couples of rectiline
  • the subject-matter of the invention is distinguished from Documents EP-A-1 167 192 and US 2002/017077 A1 by the following two groups of features:
  • thermosealing devices comprises longitudinal thermosealing devices.
  • the equipment is constructed for allowing an automatic regulability, also of an elastic give of the four springs, and for obtaining an ability to automatically calibrate a sealing pressure of the four thermosealing devices with the regulation of the length of the angular oscillations of the single shaft.

  1. Vorrichtung zum Verpacken rechteckiger Beutel mit steifen Ecken, umfassend
    ein rechteckiges Formrohr (R), das mit vier kleinen Rippen (1, 2, 3, 4) versehen ist, die parallel liegen und seitlich entlang der Verlängerung von zwei parallelen Seiten des Formrohres (R) vorstehen, wobei die Rippen zusammen mit zwei länglichen Seitengegenstücken (L) parallel zu zwei weiteren Seiten des Formrohres (R) angeordnet sind, um auf einem Film (F) vier vorstehende, längliche Falten (11, 12, 13, 14) zu erzeugen, die auch dann bleiben, wenn die vier kurzen Rippen (1, 2, 3, 4) enden, um den Eingriff von vier Thermosiegelvorrichtungen (21, 22, 23, 24) zuzulassen, wobei die Thermosiegelvorrichtungen (21, 22, 23, 24) in Zusammenwirken mit den Seitengegenstücken (L) aufgebaut sind, um Thermosiegeloperationen der vorstehenden, länglichen Falten des Films (F) auszuführen, der um das Rechteckformrohr (R) gewickelt wird, und somit die Versteifung der vier Ecken (S) des Beutels zu realisieren, die aus dem Verpackungsprozess des Films (F) resultiert, wobei die Vorrichtung mit einer Vierergruppe von Thermosiegelvorrichtungen (21, 22, 23, 24) aufgebaut ist, deren Betriebsbewegungen durch eine einzelne Schwingbewegung einer Einzelwelle (A) erhalten werden, die zwei Bereiche (D) mit langen Zähnen aufweist, welche jeweils mit einem Paar geradliniger Zahnstangen (31, 32, 33, 34) in Eingriff stehen, wobei die Paare geradliniger Zahnstangen die Winkelschwingungen der Welle (A) in entgegengesetzte, gleichzeitige, geradlinige Translationen der Vierergruppe von Thermosiegelvorrichtungen (21, 22, 23, 24) übertragen.
  2. Vorrichtung nach Anspruch 1,

  4. Vorrichtung nach Anspruch 3,
    wobei sie derart aufgebaut ist, dass sie eine automatische Regulierbarkeit auch einer Elastizität der vier Federn (41, 42, 43, 44) zulässt, und dass eine Fähigkeit erhalten wird, einen Siegeldruck der vier Thermosiegelvorrichtungen (21, 22, 23, 24) mit der Regulierung der Länge der Winkelschwingungen der Einzelwelle (A) automatisch zu kalibrieren.
